I had translab surgery with Drs. Cueva and Mostradimos in San Diego Kaiser last September and I would recommend them, they have experience with AN surgery and I felt confident putting my life in their hands. I don't recall exactly, but I believe Kaiser has surgeons in Northern California that are Stanford trained doctors and experienced in this field. I had confidence in my surgeons and did not research going outside the HMO, but that may also be a possibility. I am happy to provide more information about my surgery, just send me a PM.
